<!--

Adds the logic for handling a SHARED=0/1 option, which switches between static and
shared (DLL) builds.

Usage: use template "sharedopt" for your targets:

  <include file="presets/sharedopt.bkl"/>

  <lib id="mylib_static" cond="SHARED=='0'">
    <sources>mylib.cpp</sources>
  </lib>

  <dll id="mylib_shared" cond="SHARED=='1'">
    <sources>mylib.cpp</sources>
  </dll>

  <set var="MSVC6PRJ_MERGED_TARGETS">mylib=mylib_static+mylib_shared</set>
-->

<makefile>

    <set var="SHARED_DEFAULT" overwrite="0">0</set>
    <option name="SHARED">
        <values>0,1</values>
        <default-value>$(SHARED_DEFAULT)</default-value>
        <values-description>Static,DLL</values-description>
        <description>Set to 1 to build shared (DLL) version</description>
    </option>


    <!-- The SHAREDBUILDPOSTFIX variable is useful to set the BUILDDIR variable
         as done in presets/setbuilddir.bkl -->
    <set var="SHAREDBUILDPOSTFIX">
        <if cond="SHARED=='0'">static</if>
        <if cond="SHARED=='1'">shared</if>
    </set>

</makefile>
